Abstract
Namen dela je bil osnovati koncept integriranega ravnanja z odpadnimi blati in biorazgradljivimi odpadki Gorenjske regije, ki bi bil skladen z zakonodajo in ekonomsko izvedljiv. Avtorica je proučila relevantne strategije EU in RS o ravnanju s tovrstnimi odpadki, zakonodajo ter uveljavljene dobre prakse (IPPC direktiva/BAT/BREF). Preverjeni so bili alternativni sodobni postopki obdelave odpadnih blat in biorazgradljivih odpadkov ter opravljena SWOT analiza. Izvedena je bila raziskava trenutnega stanja ravnanja s tovrstnimi odpadki v Gorenjski regiji. Eksperimentalno so bile preverjene tri opcije sodobnega ravnanja. Ugotovitve so podprte s fizikalno – kemijskimi – biološkimi analizami vhodnih materialov in končnih produktov ter z lastnostmi in uporabnostjo produktov po različnih alternativah. Proučen je tudi ekonomski vidik različnih alternativ. Na osnovi dobljenih podatkov je predlagan najbolj primeren način integrirane obdelave odpadnih blat in biorazgradljivih odpadkov za območje Gorenjske regije, ki je anaerobna razgradnja s pridobivanjem bioplina ter kompostiranjem preostanka. Predvidene so vhodne količine tovrstnih odpadkov ter velikost in lokacija Centra za integrirano ravnanje z odpadnimi blati in biorazgradljivimi odpadki Gorenjske regije. V centru ob anaerobni razgradnji nastaja bioplin, ki služi za kogeneracijo električne in toplotne energije. Predvidena nazivna moč kogeneracije je 260 kW elektrike in 375 kW toplote. Obdelava pregnitega blata s kompostiranjem se izvaja v kompostarni izven centra. Na osnovi predvidenih stroškov in prihodkov je izračunana vračilna doba investicije v center, ki znaša 12 let.

Title:Planning the integrated treatment of waste sludges and biodegradable wastes in Gorenjska region : master of science thesis
Abstract:
The purpose of work was to establish the concept of integrated treatment of waste sludges and biodegradable wastes in Gorenjska region, which should be accordant with legislation and economicaly feasible. Adequate EU and RS strategies, legislation and well-known good practises (IPPC directive/BAT/BREF) were studied. Alternative contemporary proceedings for waste sludges and biodegradable wastes treatment were checked and compared by SWOT analysis. An examination of actual treatment with such kind of wastes was carried out for Gorenjska region. Three different options of contemporary biodegradable wastes and waste sludges treatment were experimentally checked. Findings were corroborated with physical – chemical – biological analyses of entry materials and final products and also with characteristics and products applicability of single option. An economic seight was studied for single option, too. In view of received data the most appropriate method for integrated treatment of waste sludges and biodegradable wastes in Gorenjska region was proposed; namely anaerobic digestion with biogas production, followed by composting of the residue. Entry quantities of waste sludges and biodegradable wastes were anticipated; also size and site of the Centre for integrated treatment of waste sludges and biodegradable wastes of Gorenjska region were suggested. In the centre considerable quantities of biogas can be produced and utilised for electricity and heat cogeneration. The coproduction was estimated of about 260 kW electricity power and 375 kW heat power. Composting of the digested sludge takes place in special unit out of the centre. On the base of expected costs and incomes the 12 years return period of investment in the centre was calculated.

Keywords:civil engineering, master of science thesis, waste water treatment plant, waste sludge, biodegradable wastes, composting, anaerobic digestion, biogas, energy
